The purpose of this work was to measure the value of maximum oxygen consumption in trail runners in laboratory conditions and the timing of the control run in specific sections of the distance on the ground differing in relief for further analysis of the data obtained for their correlation with the results of the competition. Runners (13 males, average age 29 ± 4 years, height 183.0 ± 0.5 cm, body weight 71.9 ± 5.6 kg) performed laboratory tests on the first day to determine maximum oxygen consumption and running economy. On the second day, a time trial cross-country race was held (two laps of 3.5 km each, the total climb was 486 m) to analyze the time parameters of overcoming individual sections of the route, as well as the overall result. Comparison of the time indicators for overcoming the first and second laps (19 m 40 s ± 1 m 57 s and 21 m 08 s ± 2 m 09 s, respectively, P < 0.001) allowed the author to conclude that the maximum loss of time among runners was noted on sections ascent, the minimum loss was in the descent sections (-2.5 ± 9.1 s). The inter-individual indicators of athletes differed most of all on descents (coefficient of variation > 25%), least of all – on flat ground (coefficient of variation < 10%). The result on the control run depended on the absolute and relative values of the maximum oxygen consumption (P < 0.01) and the vertical component of the uphill running speed (P < 0.001).
